BACKGROUND OF THE INVENTION

Phosphoinositides (PIs), which are phosphorylated derivatives ofphosphatidylinositol, are essential in eukaryotic cells, regulatingnuclear processes, cytoskeletal dynamics, signalling and membranetrafficking. Among the enzymes involved in PI metabolism, PI3-kinases(PI3K) have attracted special attention because of their oncogenicproperties and potential as drug targets. PI3-kinases phosphorylatephosphatidylinositols or PIs at the 3-position of the inositol ring.(Lindmo et al. Journal of Cell Science 119, 605-614, 2006). The3-phosphorylated phospholipids generated by PI3K activity bind to thepleckstrin homology (PH) domain of protein kinase B (PKB), causingtranslocation of PKB to the cell membrane and subsequent phosphorylationof PKB. Phosphorylated PKB inhibits apoptosis-inducing proteins such asFKHR, Bad, and caspases, and is thought to play an important role incancer progression. The PI3Ks are divided into classes I-III, and classI is further subclassified into classes Ia and Ib. Among these isoforms,class Ia enzymes are thought to play the most important role in cellproliferation in response to growth factor-tyrosine kinase pathwayactivation (Hayakawa et al., Bioorganic & Medicinal Chemistry 14,6847-6858, 2006). Three frequent mutations in cancer constitutivelyactivate PI3Kα and, when expressed in cells, they drive the oncogenictransformation and chronic activation of downstream signalling bymolecules such as PKB, S6K and 4E bp1 that is commonly seen in cancercells. (Stephens et al., Current Opinion in Pharmacology, 5 (4) 357-365,2005). As such, PI3-kinases are attractive targets for the treatment ofproliferative diseases.

There are several known PI3-kinase inhibitors including Wortmannin andLY294002. Although wortmannin is a potent PI3K inhibitor with a lownanomolar IC₅₀ value, it has low in vivo anti-tumor activity. (Hayakawaet al, Bioorg Med Chem, 14 (20), 6847-6858 (2006)). Recently, a group ofmorpholine substituted quinazoline, pyridopyrimidine andthienopyrimidine compounds have been reported to be effective ininhibiting PI3kinase p110α. (Hayakawa, 6847-6858). Oral dosage of amorpholine substituted thienopyrimidine compound (GDC-0941) has showntumor suppression in glioblastoma xenografts in vivo. (Folkes et al.,Journal of Medicinal Chemistry, 51, 5522-5532, 2008). The followingpublications disclose a series of thienopyrimidine, pyridopyrimidine andquinazoline based PI3-Kinase inhibitors: WO 2008/073785; WO 2008/070740;WO 2007/127183; U.S. Patent Publication 20080242665.

Histone acetylation is a reversible modification, with deacetylationbeing catalyzed by a family of enzymes termed histone deacetylases(HDACs). HDAC's are represented by 18 genes in humans and are dividedinto four distinct classes (J Mol Biol, 2004, 338:1, 17-31). Inmammalians class I HDAC's (HDAC1-3, and HDAC8) are related to yeast RPD3HDAC, class 2 (HDAC4-7, HDAC9 and HDAC10) related to yeast HDA1, class 4(HDAC11), and class 3 (a distinct class encompassing the sirtuins whichare related to yeast Sir2).

Csordas, Biochem. J., 1990, 286: 23-38 teaches that histones are subjectto post-translational acetylation of the, ε-amino groups of N-terminallysine residues, a reaction that is catalyzed by histone acetyltransferase (HAT1). Acetylation neutralizes the positive charge of thelysine side chain, and is thought to impact chromatin structure. Indeed,access of transcription factors to chromatin templates is enhanced byhistone hyperacetylation, and enrichment in underacetylated histone H4has been found in transcriptionally silent regions of the genome(Taunton et al., Science, 1996, 272:408-411). In the case of tumorsuppressor genes, transcriptional silencing due to histone modificationcan lead to oncogenic transformation and cancer.

Several classes of HDAC inhibitors currently are being evaluated byclinical investigators. Examples include hydroxamic acid derivatives,Suberoylanilide hydroxamic acid (SAHA), PXD101 and LAQ824, are currentlyin the clinical development. In the benzamide class of HDAC inhibitors,MS-275, MGCD0103 and CI-994 have reached clinical trials. Mourne et al.(Abstract #4725, AACR 2005), demonstrate that thiophenyl modification ofbenzamides significantly enhance HDAC inhibitory activity against HDAC1.

Mammalian Target of Rapamycin (mTOR) is a signaling protein which isdownstream of multiple signaling pathways, including the PI3K/Aktpathway. Cell signaling through mTOR controls a variety of cellularresponses, including responses to nutrients and growth factors. mTORinhibitors are currently in clinical use for the prevention oftransplant rejection. However, the ability of these compounds to shrinktumors suggests their potential use as anti-cancer agents. The effect ofmTOR inhibitors on cancer cells may arise from inhibition of the PI3/Aktpathway. Inhibition of mTOR also lowers VEGF levels, resulting in anantiangiogenic effect that may also contribute to tumor shrinkage.Recent research suggests that the inhibition of multiple targets in thePI3K/Akt pathway provides improved anticancer activity. Thus, compoundswhich inhibit both PI3K and mTOR are desirable.

Certain cancers have been effectively treated with such a combinatorialapproach; however, treatment regimes using a cocktail of cytotoxic drugsoften are limited by dose limiting toxicities and drug-druginteractions. More recent advances with molecularly targeted drugs haveprovided new approaches to combination treatment for cancer, allowingmultiple targeted agents to be used simultaneously, or combining thesenew therapies with standard chemotherapeutics or radiation to improveoutcome without reaching dose limiting toxicities. However, the abilityto use such combinations currently is limited to drugs that showcompatible pharmacologic and pharmacodynamic properties. In addition,the regulatory requirements to demonstrate safety and efficacy ofcombination therapies can be more costly and lengthy than correspondingsingle agent trials. Once approved, combination strategies may also beassociated with increased costs to patients, as well as decreasedpatient compliance owing to the more intricate dosing paradigmsrequired.

SUMMARY OF THE INVENTION

The present invention relates to deazapurines, thienopyrimidines andfuropyrimidines with zinc-binding moiety based derivatives and their usein the treatment of PI3K related diseases and disorders such as cancer.The compounds of the present invention may further act as HDAC or matrixmetalloproteinase (MMP) inhibitors by virtue of their ability to bindzinc ions. Surprisingly these compounds are active at multipletherapeutic targets and are effective for treating disease. Moreover, insome cases it has even more surprisingly been found that the compoundshave enhanced activity when compared to the activities of combinationsof separate molecules individually having the PI3-Kinase and HDACactivity. In other words, the combination of PI3-kinases and HDACinhibitors into a single molecule may provide a synergistic effect ascompared to the PI3-kinases. In another embodiment, certain compounds ofthe present invention also inhibit mTor in addition to having PI3-Kinaseand HDAC activity.

Moreover, the efficacy of single-agent PI3K pathway inhibitors islimited by the presence of primary/acquired genetic alterations andactivation of multiple pro-survival and growth pathways (Engelman (2009)Nature Reviews Cancer, 9: 550-562) Inhibition of PI3K by single-agentPI3K pathway inhibitors can actually upregulate signaling of theRAF-MEK-ERK pathway by the release of negative feedback loops. Thecompounds of the invention, by virtue of their integrated PI3K/HDACinhibitory activities, provide the potential to overcome the limitationsin the treatment of cancers with single-target PI3K inhibitors. Thecompounds of the invention may disrupt cancer networks in in vivo and invitro experiments, resulting from durable inhibition of thePI3K-AKT-mTOR pathway, the inhibition of the RAF-MEK-ERK pathway, andthe downregulation of receptor tyrosine kinase (RTK) protein levels. Inaddition, the compounds of the invention may induce cell cycle arrestand apoptosis resulting from the upregulation of tumor suppressors p53and p21. Accordingly, compounds of the invention have the potential toovercome primary and acquired drug resistance and may be moreefficacious than mono-treatment with single-agent PI3K pathwayinhibitors in clinical applications.

For example, cancersinclude, but are not limited to, mesothelioma, leukemias and lymphomassuch as cutaneous T-cell lymphomas (CTCL), noncutaneous peripheralT-cell lymphomas, lymphomas associated with human T-cell lymphotrophicvirus (HTLV) such as adult T-cell leukemia/lymphoma (ATLL), B-celllymphoma, acute nonlymphocytic leukemias, chronic lymphocytic leukemia,chronic myelogenous leukemia, acute myelogenous leukemia, lymphomas, andmultiple myeloma, non-Hodgkin lymphoma, acute lymphatic leukemia (ALL),chronic lymphatic leukemia (CLL), Hodgkin's lymphoma, Burkitt lymphoma,adult T-cell leukemia lymphoma, acute-myeloid leukemia (AML), chronicmyeloid leukemia (CML), or hepatocellular carcinoma. Further examplesinclude myelodisplastic syndrome, childhood solid tumors such as braintumors, neuroblastoma, retinoblastoma, Wilms' tumor, bone tumors, andsoft-tissue sarcomas, common solid tumors of adults such as head andneck cancers (e.g., oral, laryngeal, nasopharyngeal and esophageal),genitourinary cancers (e.g., prostate, bladder, renal, uterine, ovarian,testicular), lung cancer (e.g., small-cell and non small cell), breastcancer, pancreatic cancer, melanoma and other skin cancers, stomachcancer, brain tumors, tumors related to Gorlin's syndrome (e.g.,medulloblastoma, meningioma, etc.), and liver cancer. Additionalexemplary forms of cancer which may be treated by the subject compoundsinclude, but are not limited to, cancer of skeletal or smooth muscle,stomach cancer, cancer of the small intestine, rectum carcinoma, cancerof the salivary gland, endometrial cancer, adrenal cancer, anal cancer,rectal cancer, parathyroid cancer, and pituitary cancer. Additionalcancers that the compounds described herein may be useful in preventing,treating and studying are, for example, colon carcinoma, familiaryadenomatous polyposis carcinoma and hereditary non-polyposis colorectalcancer, or melanoma. Further, cancers include, but are not limited to,labial carcinoma, larynx carcinoma, hypopharynx carcinoma, tonguecarcinoma, salivary gland carcinoma, gastric carcinoma, adenocarcinoma,thyroid cancer (medullary and papillary thyroid carcinoma, renalcarcinoma, kidney parenchyma carcinoma, cervix carcinoma, uterine corpuscarcinoma, endometrium carcinoma, chorion carcinoma, testis carcinoma,urinary carcinoma, melanoma, brain tumors such as glioblastoma,astrocytoma, meningioma, medulloblastoma and peripheral neuroectodermaltumors, gall bladder carcinoma, bronchial carcinoma, multiple myeloma,basalioma, teratoma, retinoblastoma, choroidea melanoma, seminoma,rhabdomyosarcoma, craniopharyngeoma, osteosarcoma, chondrosarcoma,myosarcoma, liposarcoma, fibrosarcoma, Ewing sarcoma, and plasmocytoma.In one aspect of the invention, the present invention provides for theuse of one or more compounds of the invention in the manufacture of amedicament for the treatment of cancer.

In one embodiment, the compounds of the invention are used to treat ahematological cancer or hematological precancerous conditions.Hematological cancers include leukemias, lymphomas and multiple myeloma.Examples include lymphocytic leukemias, such as acute lymphocyticleukemia, including precursor B acute lymphoblastic leukemia, precursorT acute lymphoblastic leukemia, Burkitt's leukemia, and acutebiphenotypic leukemia; and chronic lymphocytic leukemia, includingB-cell prolymphocytic leukemia; and myologenous leukemias, such as acutemyologenous leukemia, including acute promyelocytic leukemia, acutemyeloblastic leukemia, and acute megakaryoblastic leukemia; and chronicmyologenous leukemia, including chronic monocytic leukemia; acutemonocytic leukemia. Other leukemias include hairy cell leukemia; T-cellprolymphocytic leukemia; large granular lymphocytic leukemia; and AdultT-cell leukemia. Lymphomas include Hodgkin's lymphoma and Non-Hodgkin'slymphoma, including B-cell lymphomas, T-cell lymphomas, such ascutaneous T-cell lymphoma, and NK cell lymphomas. Hematologicalprecancerous conditions include myelodysplastic syndrome andmyeloproliferative disorders, such as primary myelofibrosis,polycythemia vera, and essential thrombocythemia.

Compounds of the invention have been shown to induce lymphopenia and aretherefore of use for removing circulating cancer cells of lymphocyticlineage. Such compounds are also of use for treating autoimmunedisorders or for modulating an immune response.

In one embodiment, the invention provides a method for reducing thecirculating lymphocyte count in a subject, comprising administering tothe subject an effective amount of a compound of the invention. In apreferred embodiment, the reduced circulating lymphocyte count isreversible, that is, the circulating lymphocyte count returns to thenormal range after dosing with the compound of the invention is stopped.In one embodiment, the reduced circulating lymphocyte count is below thenormal range and the subject is lymphopenic. Preferably, the subjectderives a therapeutic or prophylactic benefit from the reducedcirculating lymphocyte count. Such subjects include those suffering froma hematologic disease, such as a hematologic cancer, those sufferingfrom an autoimmune disorder, and those requiring modulation of an immuneresponse such as patients suffering from diabetes or organ transplantrecipients. In a human subject, the circulating lymphocyte count, forexample, B-lymphocytes, T-lymphocytes or both, can drop from a normalrange to a lymphopenic range. In certain diseases the circulatinglymphocyte count is abnormally high. In such diseases, the circulatinglymphocyte count can be reduced to the normal range or to a lymphopenicstate.

In one embodiment, the present invention includes the use of one or morecompounds of the invention in the manufacture of a medicament thatprevents further aberrant proliferation, differentiation, or survival ofcells. For example, compounds of the invention may be useful inpreventing tumors from increasing in size or from reaching a metastaticstate. The subject compounds may be administered to halt the progressionor advancement of cancer or to induce tumor apoptosis or to inhibittumor angiogenesis. In addition, the instant invention includes use ofthe subject compounds to prevent a recurrence of cancer.

This invention further embraces the treatment or prevention of cellproliferative disorders such as hyperplasias, dysplasias andpre-cancerous lesions. Dysplasia is the earliest form of pre-cancerouslesion recognizable in a biopsy by a pathologist. The subject compoundsmay be administered for the purpose of preventing said hyperplasias,dysplasias or pre-cancerous lesions from continuing to expand or frombecoming cancerous. Examples of pre-cancerous lesions may occur in skin,esophageal tissue, breast and cervical intra-epithelial tissue.

“Combination therapy” includes the administration of the subjectcompounds in further combination with other biologically activeingredients (such as, but not limited to, a second and differentantineoplastic agent) and non-drug therapies (such as, but not limitedto, surgery or radiation treatment). For instance, the compounds of theinvention can be used in combination with other pharmaceutically activecompounds, preferably compounds that are able to enhance the effect ofthe compounds of the invention. The compounds of the invention can beadministered simultaneously (as a single preparation or separatepreparation) or sequentially to the other drug therapy. In general, acombination therapy envisions administration of two or more drugs duringa single cycle or course of therapy.

In one aspect of the invention, the subject compounds may beadministered in combination with one or more separate agents thatmodulate protein kinases involved in various disease states. Examples ofsuch kinases may include, but are not limited to: serine/threoninespecific kinases, receptor tyrosine specific kinases and non-receptortyrosine specific kinases. Serine/threonine kinases include mitogenactivated protein kinases (MAPK), meiosis specific kinase (MEK), RAF andaurora kinase. Examples of receptor kinase families include epidermalgrowth factor receptor (EGFR) (e.g. HER2/neu, HER3, HER4, ErbB, ErbB2,ErbB3, ErbB4, Xmrk, DER, Let23); fibroblast growth factor (FGF) receptor(e.g. FGF-R1, GFF-R2/BEK/CEK3, FGF-R3/CEK2, FGF-R4/TKF, KGF-R);hepatocyte growth/scatter factor receptor (HGFR) (e.g. MET, RON, SEA,SEX); insulin receptor (e.g. IGFI-R); Eph (e.g. CEK5, CEK8, EBK, ECK,EEK, EHK-1, EHK-2, ELK, EPH, ERK, HEK, MDK2, MDK5, SEK); Ax1 (e.g.Mer/Nyk, Rse); RET; and platelet-derived growth factor receptor (PDGFR)(e.g. PDGFα-R, PDGβ-R, CSF1-R/FMS, SCF-R/C-KIT, VEGF-R/FLT, NEK/FLK1,FLT3/FLK2/STK-1). Non-receptor tyrosine kinase families include, but arenot limited to, BCR-ABL (e.g. p43^(abl), ARG); BTK (e.g. ITK/EMT, TEC);CSK, FAK, FPS, JAK, SRC, BMX, FER, CDK and SYK.

In another aspect of the invention, the subject compounds may beadministered in combination with one or more separate agents thatmodulate non-kinase biological targets or processes. Such targetsinclude histone deacetylases (HDAC), DNA methyltransferase (DNMT), heatshock proteins (e.g. HSP90), hedgehog pathway-related proteins (e.g.sonic hedgehog, patched, smoothened), and proteosomes.

In order to prolong the effect of a drug, it is often desirable to slowthe absorption of the drug from subcutaneous or intramuscular injection.This may be accomplished by the use of a liquid suspension ofcrystalline or amorphous material with poor water solubility. The rateof absorption of the drug then depends upon its rate of dissolution,which, in turn, may depend upon crystal size and crystalline form.Alternatively, delayed absorption of a parenterally administered drugform is accomplished by dissolving or suspending the drug in an oilvehicle. Injectable depot forms are made by forming microencapsulematrices of the drug in biodegradable polymers such aspolylactide-polyglycolide. Depending upon the ratio of drug to polymerand the nature of the particular polymer employed, the rate of drugrelease can be controlled. Examples of other biodegradable polymersinclude poly(orthoesters) and poly(anhydrides).
